Why Fewer Women Receive Deep Brain Stimulation

Deep Brain Stimulation (DBS) is often described as a life-changing procedure for people with Parkinson’s, capable of significantly reducing tremors and improving mobility when medications are no longer enough. However, a troubling statistic has emerged from recent research at the University of Colorado Anschutz Medical Campus: men receive 70% of these surgeries, while women are being left behind. The study, which looks into the disparities in Parkinson’s care, highlights that this gap isn't caused by biological differences in how the surgery works, but rather by a complex web of social, economic, and systemic barriers. The Referral Barrier The journey to the operating theatre begins with a referral from a neurologist. Research suggests that women are less likely to be referred for a surgical consultation in the first place. This is often due to "clinical bias," where symptoms in women are sometimes perceived differently or managed more conservatively with medication for longer periods than in men. The "Caregiver" Paradox One of the most significant hurdles is the role of caregiving. Traditionally, women are more likely to be the primary caregivers for their spouses or families. When a man develops Parkinson’s, he often has a female partner to navigate his appointments, manage his medications, and advocate for surgery. Conversely, when a woman has the condition, she is less likely to have that same level of logistical support. Surgery requires a strong support system for the recovery period and for the subsequent "programming" appointments where the brain stimulator is fine-tuned. Without a dedicated caregiver to assist with travel and home care, many women feel they cannot opt for the procedure. Economic and Social Factors The study also points to economic disparities. Women are more likely to live alone in older age and may have fewer financial resources to cover the indirect costs of surgery, such as transport to specialist centres. Furthermore, there is a documented "communication gap" where women may be less likely to "demand" surgical interventions, instead focusing on maintaining their current level of function to continue their caregiving duties for others. Different Symptoms, Different Priority? Parkinson's symptoms can manifest differently between genders. While men often present with the "classic" resting tremor that is highly responsive to DBS, women may experience more "non-motor" symptoms, such as anxiety or depression, or different types of balance issues. Because surgical success is often measured by the reduction of visible tremors, women whose primary struggles are less "visible" may be overlooked as candidates. Why Representation Matters The 70/30 split in surgery is particularly concerning because when women do receive DBS, the outcomes are often excellent. In fact, some data suggests that women may experience even greater improvements in quality of life post-surgery than men. Addressing this gap requires a multi-front approach: Clinician Awareness: Neurologists must be trained to recognise and check for their own unconscious biases during the referral process. Expanded Support Networks: Creating community-based support for people who live alone could help more women access the recovery care they need. Targeted Education: Ensuring that women are fully informed about the benefits of DBS early in their diagnosis, rather than waiting until the condition is advanced. By dismantling these barriers, the medical community can ensure that this "gold standard" of Parkinson’s treatment is accessible to everyone, regardless of gender.
